TYPOGRAPHICAL, SLUG CASTING MACHINE Filed March 17,` 1954 Patented Mar.24, 1936 TYPOGRAPHICAL SLUG CASTING MACHINE William Fairall Gorse,Altrincham, and Richard Henry Scott, Enfield, England, assignors toLinotype and Machinery Limited, London, England, a company of EnglandApplication March 17, 1934, Serial No. 716,114 In Great Britain April 6,1933 16 Claims.

This invention relates to typographical slug casting machines such asthose known commercially under the registered trade-mark Linotype,wherein circulating matrices are composed in line and the composed linepresented to a slotted mould for the casting of the type bar or slug,the line, during the casting operation, being positioned between a pairof line clamping jaws which are ordinarily set to receive a line ofpredetermined length.

In order to provide for the production of slugs with blank spaces at theends, for quadding or centring, without the necessity of filling out thecomposed line with blanks or quads, it has been proposed to providemeans for automatically moving one or other, or both, of the jawsinwardly for the clamping of composed lines of less than full length. Inthese arrangements, however, the composed line itself acts as a stop forthe inward movement of the jaw or jaws, so

that the length of the blank space at the respective end of the slug isdetermined by the length of the composed line, subject in some cases, toa limited outward movement of the jaws to allow for a predeterminedmaximum expansion of the line during justification when expansiblespacebands are used.

The object of the present invention is to provide means independent ofthe composed line,

adjustable to determine the extent of the inward movement of the movablejaw or jaws, whereby the length of the blank space, or spaces producedon the slugs, is determined by the adjustment of the jaw or jaws,instead of by the length of the line, so that a denite indent may beproduced on the cast slug, the end of the slug at which such indent isproduced being determined by the particular jaw in connection with whichthe quadding adjustment is provided.

The invention may be carried out conveniently by arranging an adjustablestop in the path of the respective jaw during its inward movement, or inthe path of a member of the jaw adjusting mechanism, which can be set todetermine the desired extent of said inward movement or thrown out ofaction when not required.

The invention is hereinafter more particularly described with referenceto the accompanying drawing showing one constructional form thereof. Inthe said drawing:-

Figure 1 is an elevation of the pertinent parts frame of the machinebeing indicated in dotand-dash lines;

Figure 3 is an elevation as seen from the lefthand side of Figure 1, ofthe means for adjusting the stop, some of the parts being broken away 5.and some omitted.

According to the constructional form of apparatus illustrated in thedrawing, the inward movement of the jaws I, 2, for quadding or centring,is effected by-a vertically movable operat- 10 ing rod 3. This rod isoperatively connected with or disconnected from the respective jawsthrough levers Il, 5, pivoted to the vice frame 6, and having on theirshorter arms pins extending beneath a collar 26 angularly adjustable atthe 15 upper end of the rod 3. 'Ihe collar 26 is formed with segmentalprojections which are brought into and out of engaging relationship withthe pins by angular adjustment of the collar so that either or both ofthe jaws I, 2, may be moved in- 20 wardly for quadding or centring bythe operation of the rod.

As this arrangement, and the devices for operating the rod, do not perse constitute part of the p-resent invention, it is deemed unneces- 25sary to include herein any further detailed description or illustrationthereof.

In applying the invention to the constructional form of quadding andcentring apparatus above referred to, the adjustable stop is preferably30 adapted to engage with a stop member I secured to the jaw-operatingrod 3, and in the preferred arrangement now to be described, theadjustable stop and its adjusting devices are provided in the form of aself-contained unit supported in a 35 bracket 8 which can be attached tothe vice frame 6 of the machine.

Referring first to Figure 1, the adjustable stop 9 is carried by a barI0 which is slidable in a guideway on the bracket 8 constituted by side40 members II and keeper plates I2. The adjusting devices for the stop 9comprise a lever I3, one end of which turns about a fixed pivot I4 onthe bracket 3. The free end of the lever I3 is pivoted to a link I5which is in turn pivoted to a 45 stud IB (see particularly Figure 3),which is adjustable along a slot II in the bracket 8. The lever I3 isprovided with a pin I8 located between the ends of the lever projectingrearwardly therefrom into engagement with a forked brack- 50 et I9secured to the bar Ill.

As shown best in Figure 3, the stud I6 extends through the slot Il inthe bracket 8, and at its outer end is fitted with an adjustable knob 20which is axially movable on the stud I6 but is 55 angularly fastthereto. A spring 2l, acting between the lmob 2i! and a collar 22 on thestud I6, normally urges the knob 20 towards the bracket 8, and for thepurpose of retaining the knob in any of its adjusted positions a rack 23is formed on or secured to the bracket 8, this rack 23 extendingparallel with the slot Il so as to engage teeth formed on the inner faceof the knob 20, whatever the position of the latter along the said slot.A scale 24 arranged parallel with the slot il may be secured to thebracket 8 for cooperation with a pointer 25 on the knob 2G indetermining the necessary adjustment for an indent of any desiredlength.

The constructional form of the invention above described operates asfollowsz-When, for example, an indent of 6 ems, is required on a slug ofnormal length, the stud l is adjusted along the slot ll until thepointer 25 registers with the 6 em mark on the scale 2d, and locked inthat position by the action of the spring 2l on the release of the knob2G at the completion of the adjustment. Through the consequent movementof the lever i3 the bar lil is adjusted to set the stop 9 at the desireddistance below the stop 'l on the jaw-operating rod 3. Thejust-described position oi adjustment is indicated in Figure l, whereinalso both jaws l, E, are represented as connected to the jaw-operatingrod 3; thus, when the rod 3 is moved downwardly to effect the inwardmovement of the jaws, such downward movement will be arrested by thecontact of the stop 'l with the stop S, and the jaws l, 2, consequentlyheld in the position indicated in dotted lines in Figure l to produce anindent of 6 ems at both ends of the slug to be cast. A correspondingindent may, oi course, be produced at either end of the slug as desiredby connecting only the respective jaw to the rod 3. When it is desi-redto operate the quadding and centring devices normallly, i. e., withoutproducing a predetermined indent, the stop 9 may be rendered inoperativeby setting its adjusting devices in the lowermost position indicated bydot-and-dash lines in Figure l. In cases where the quadding and centringdevices are arranged to permit, in normal operation, an outward yieldingof the jaws during the justication of lines containing spacebands, theindenting stop may be used in conjunction with means for limiting orpreventing such outward yielding, which means, however, constitute nopart of the present invention.

`It is to be understood that the constructional form of the inventionand of the quadding and centring devices above described and illustratedin the accompanying drawing has been chosen merely as convenientexamples, and that the invention contemplates variations in the form ofthe stop and its adjusting devices to suit any particular form ofjaw-operating mechanism to which the invention is to be applied.
